LIFE-BOAT.

Application filed September 25, 1915.

To all 'whom t may concern:

Be it known that I, KENJIRO OKAMURO, a subject of the Emperor of Japan,residing at Manoa, city of Honolulu, in the Island of Honolulu andTerritory 0f Hawaii, have invented certain new and useful Improvementsin Life-Boats; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to life boats.

The object of the invention is to provide a life boat embodying animproved construction for preventing same from capsizing in a rough sea.

A further object of the invention is to provide a life boat which willbe simple in construction and efficient in use, it being noted that theportion of the structure of the boat designed to prevent capsizing canbe associated with an ordinary boat with eflicient results.

lVith the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference -will be had to theaccompanying drawings wherein like characters of refer ence denotecorresponding parts in the several views, and in which- Figure l is aplan View of a life boat constructed in accordance with the invention;

Fig. 2, a side View of a fragment of what is shown in Fig. l on anenlarged scale;

Fig. 3, a section on the line 3v3 of Fig. 2, and

Fig. et, a section on the line 4 4 of F ig. 2.

Referring to the drawings A indicates a boat of the usual shape employedin the construct-ion of life boats. Secured to either side of the boat Ais a float or buoy B of Speceation of Letters Patent.

substantially cylindrical shape and having its ends tapered to a pointas at l0. These floats or buoys B may be constructed of any suitablematerial such as thin metal and are of course hollow to provide thenecessary buoyancy. Each iioat B is secured against the related side ofthe boat A by means of a plurality of U-shaped straps ll the ends ofwhich are secured to the boat by means of bolts l2. Each of the strapsll is provided with a longitudinal passage 13 therethrough and extendingthrough these passages is a bar 14E which is disposed in spaced relationto the adjacent float B and serves to protect the latter against damageas will be obvious. By tapering the ends of each float it will beapparent that they will offer little resistance to the movement of theboat while the buoyacy of the floats will effectively resist anytendency of the boat to capsize in a rough sea.

What is claimed is An attachment for a boat, consisting of a pair ofcylindrical float elements and adapted to be secured to opposite sidesof the boat in symmetrical relation and to abut said sides, and securingmeans for each float element consisting of a plurality of spa-cedlongitudinally alined brackets, each bracketI shaped to conform closelyto the curvature of the float element and to embrace the `float elementthrough substantially the entire circumference thereof spanned by thebracket, and each bracket terminating in oppositely bent portionsadapted to be secured against the boat side, said brackets furtherprovided upon the outer sides of the float elements with openingsadapted to receive guard bars, and guard bars lodged in said openings inspaced relation to said float elements.

In testimony whereof, I aiiiX my signature, in the presence of twowitnesses.
